Constructor & Destructor Documentation

WikiExporter::__construct (   $db,
  $history = self::CURRENT,
  $buffer = self::BUFFER,
  $text = self::TEXT 
)

If using WikiExporter::STREAM to stream a large amount of data, provide a database connection which is not managed by LoadBalancer to read from: some history blob types will make additional queries to pull source data while the main query is still running.

Parameters
IDatabase$db
int | array$historyOne of WikiExporter::FULL, WikiExporter::CURRENT, WikiExporter::RANGE or WikiExporter::STABLE, or an associative array:
  • offset: non-inclusive offset at which to start the query
  • limit: maximum number of rows to return
  • dir: "asc" or "desc" timestamp order
int$bufferOne of WikiExporter::BUFFER or WikiExporter::STREAM
int$textOne of WikiExporter::TEXT or WikiExporter::STUB

WikiExporter::outputPageStream (   $resultset)
protected

Runs through a query result set dumping page and revision records.

The result set should be sorted/grouped by page to avoid duplicate page records in the output.

Should be safe for streaming (non-buffered) queries, as long as it was made on a separate database connection not managed by LoadBalancer; some blob storage types will make queries to pull source data.

Parameters
ResultWrapper$resultset
